According to the Encyclopedia of Britain by Bamber Gascoigne (1993), it was Catherine Winkworth who, learning of General Charles James Napier's ruthless and unauthorised, but successful campaign to conquer the Indian province of Sindh, "remarked to her teacher that Napier's despatch to the governor-general of India, after capturing Sindh, should have been Peccavi" (Latin for "I have sinned": a pun on "I have Sindh"). She sent her joke to the new humorous magazine Punch, which printed it on 18 May 1844. She was then sixteen years old.
